LU BRICATOR.

SPECIFICATION forming part of Letters Patent No. 431,910, dated July 8, 1890.

Application filed April 9, 1889. Serial No. 306,511. (No model.)

To all whom t may concern:

Be it known that we, RICHARD J. MCCARTY and CLARENCE A. BURTON, both residing at Kansas City, in the lcounty of Jackson and State of Missouri, have invented new and useful Improvements in Lubricating J ournals;V

to keep thc axle and bearing constantly lubricated for a longer time than is possible with axle-boxes of the now well-known forms, and, sccond,to more eifectually and economically lubricate the axle. These objects are accomplished by providing means whereby the many disadvantages arising from the use of the ordinary forms of journal-boxes are counteracted.

To these ends our invention consists, first, in providing` a journal-box having preferably three distinct or independent chambers formed transversely of the box and having openings at the bottom through the wall of each chamber, so that each completely surrounds the axle, and, secondly, in supplying to the axle at its bearings 'separately-that is to say, from different receptacles-liquid lubricant and solid or viscous lubricant.

Suitable bearings and other minor details of construction will be hereinafter more fully described with reference to the accompanying drawings, and then more specifically pointed out in the claims.

In said drawings, Figure I is a top view of our improved j Ournal-box with the cover open, showing the inner arrangement of the several parts. lFig. II. is a section taken on line II II, Fig. I, looking in the direction of the arrows. Fig. III is a section taken on line III III of Fig. I, looking in the direction of the arrow.

A is the journal-box, having pivotal bearings a a and cover B. The cover B has hinges b b', and is made large enough to overlap the sides of the box, so as to more eectually keep out of the box all dirt, dust, water, die., which would injure smooth bearing-surfaces. The box Ais divided into three separate chambers or compartments 1,2, and 3 by diaphragms E and F. The outer chambers 1 3 are small, while the inner chamber 2 is large for the reception of the bearing or pillow block D. The form of these diaphragms E F is shown in Fig. III. The lower end of the diaphragm extends down just far enough to overlap the top of the bearing or pillow-block D, which rests on the elevated seat 4 of the box, thus leaving only a circular opening between the two outer chambers 1 and 3 and the inner chamber 2. This opening is just large enough for the free passage and revolution of the axle C.

, The bearing or pillow-block D, which rests upon the raised seat 4, is of the usual shape and construction, being formed of Babbitt metal or other suitable material. The seati: and bearing D are j ust thelengt-h and breadth of the inner chamber 2, so that the pillowblock when dropped into said chamber 2 lits snugly and has ample support at all points from the seat 4. The seat. l is cast integral with the rest of the box.

On the inside of the outer wall of the chamber 3 is formed a boss 5, which serves either as an abutment for the end of the axle C or as a support for a steel plate G, which serves as the end bearing of axle C. The bottom of chamber l has a curved surface to facilitate the packing of said chamber tightly. The opening in the outer wall of chamber l for the admission of the shaft is made enlarged or elongated, so as to permit the shaft to follow thepillow-block D as it wears away. In practiced have found that some journals require but one kind of lubricant. In such cases a thin or thick lubricant alone may be used in connection with the packing, and but two compartments are therefore provided. I therefore do not confine myself to the use of three compartments, but mean by the term plurality two or more.

Having thus fully described the construction and arrangement of the several parts, the box is used as follows: The axle C being properly placed in its bearings-that is, so as to rest on bearing D and abut against plate G-the outer chamber 1 is tightly packed IOO with Wool, waste, or other packing, which is then thoroughly saturated with oil. The large chamber is then filled with a lubricating compound of the proper consistencythat is, of such consistency that it willnot be thick enough to arch over the axle as it is used up and not thin enough to soak through.

the packing in chamber l and drip out. The other outer chamber 3 is then filled with a lighter lubricating compound. This lubricant may be fluid oil or any other suitable material which will feed properly. The lubricant in this chamber 3 serves the double purpose of lubricating the end of shaft C and the abutment or steel plate and of Working through on the shaft underneath the heavy lubricant in the larger chamber, thus more thoroughly lubricating the axle and the bearing D and increasing the tendency of the heavy lubricating compound to feed down upon the shaft in case it should not do so of its own accord.

In the drawings we have shown our improvements applied to the form of journal-` boxes used for the axles of cable-carrying sheaves of cable railways; but it is evident that they are vequally as Well applicable to other forms of journal-boxes for other uses. From this construction and arrangement a journal-box is formed which produces the most satisfactory results. The bearings are kept thoroughly and constantly lubricated and require comparatively little attention to keepv lthem in working order.

Among the many and manifold advantages derived from the use of our improvements over the Well-known forms are the following: The bearings are thoroughly protected from dust, dirt, water, &c. The lubricant is prop- 'erly confined, so that it will not escape from the box and leave the bearings dry. This also makes the box economical, as the lubricant is not wasted and the box requires very little attention for replacing the lubricant.

Having thus fully described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:

l. The method of lubricating journals in a journal-box, consisting' in supplying separately lubricants of different degrees of con sistency to the journal in said box, said lubricants being placed in order of consistencythat is to say, the lubricant of greater consistency being in front of the lubricant of less consistency-whereby the latter is retained by the former, as explained.

2. The herein-described method of lubricating journals, which consists in supplying separately solid or thick lubricant to the forward part of the axle in such manner as to close around the same and a liquid lubricant behind the solid, substantially as and for the purposes set forth.

3. A journal-box comprising a number of independent compartments, through all of which the journal passes in series, each adapted to completely surround the journal and being open at top for the reception of lubricant, all substantially as explained.

et. In a journal-box, the combination of receptacle l, having curved bottom, receptacle 2, having raised seat 4 for support of bearing D, and receptacle 3, having' abutment 5 at end, and plate G, resting against abutment 5 for the end bearing of shaft C, all substantially as and for the purpose set forth.

5. In a journal-box, the combination of receptacles l 2 3, diaphragms E F, separating said receptacles, removable bearing D, adapted to rest onseat 4 in receptacle 2, and support-shaft C, boss 5, and plate G, forming end bearing for shaft C, and cover B,for covering thethree receptacles,substantially as set forth.

6. A journal-box havingthe three compartments, enlarged openings in the outer wall of the forward compartment and in the walls between the compartments, and a pillow-block in the middle compartment, whereby the bearing is confined to the pillow-block and the axle may follow the same block as it wears, as shown and described.
